Abstract: <P>PROBLEM TO BE SOLVED: To provide a method for conveying a plate body assuring straight advance conveying property when the four sides of the plate body, particularly a wooden plate body of a plywood and a laminated veneer lumber is sawed or the plate body is sawed into a plurality of pieces by reducing the positional displacement of the plate body in a direction orthogonal to the carrying direction of the plate body fed when the plate body is conveyed, and its device.  <P>SOLUTION: A cut of any depth is formed in the plate body by a saw disposed on one side in the direction orthogonal to the conveying direction during conveyance. The cut is formed in a generally rectangular shape in cross section. In the plate body, a guide body extendedly disposed along the conveying direction is installed in the cut formed in the lower surface thereof. The cross sectional shape of the guide body in the direction orthogonal to the conveying direction is formed in the generally same shape as the cross sectional shape of the cut formed in the plate body in the direction orthogonal to the conveying direction. When the plate body is pressed against the guide body, the plate body is conveyed while one side face of the cut and one side face of the guide body come into contact and generally parallel with each other.  <P>COPYRIGHT: (C)2004,JPO

Filed: 2002-10-28
Abstract: <P>PROBLEM TO BE SOLVED: To stably form an image of high quality, and to prolong the life of an image carrier by removing filming matter while suppressing the shaving of the image carrier surface layer to the absolute minimum, as for an electrophotographic image forming apparatus.  <P>SOLUTION: In a graphic chart showing the relationship between the number of copied sheets and the quantity of the shaven image carrier surface (quantity of shaven photoreceptive layer), the gradient of a segment linking a point P2 where the quantity of the shaven image carrier surface is Yn+1 for the number of copied sheets Xn+1 and another point P3 where the quantity of the shaven image carrier surface is Yn+2 for the number of copied sheets Xn+2 is derived. Since the gradient between the two points is smaller than a reference gradient, a function of removing the filming matter is enhanced by increasing the linear velocity difference between the image carrier surface and a developing roller surface in order to remove the filming matter on the photoreceptor surface.  <P>COPYRIGHT: (C)2004,JPO

Abstract: <P>PROBLEM TO BE SOLVED: To provide an information recording/reproducing apparatus and information reproducing method capable of quickly completing the recording operation of information data even though the external disturbance, etc., are exerted.  <P>SOLUTION: In accordance with a demodulation timing pulse, a synchronizing signal and address data indicating the address are respectively demodulated from a reading signal read out from a recording medium, and the error correcting process is applied to the address data to obtain corrected address data, and also the discrimination is made whether these corrected address data are the proper address or not. At this point, as for the execution of the synchronizing process to make the demodulation timing pulse synchronize with the synchronizing signal when a period of the synchronizing signal is equal to a prescribed period, if the corrected address data are determined as the proper address, the execution of the re-synchronizing process is made on standby after that, till the corrected address data are determined as the wrong address. By such operation, the recording of the information data can be quickly completed without interrupting the recording operation since the re-synchronizing process is not executed in such a degree that the synchronizing signal is temporarily disturbed by the external disturbance.  <P>COPYRIGHT: (C)2004,JPO
